IMPROVEMENTIN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. [85,497, dated December19, 1876; application filed January 2, 1875.

To all whom 'itmay concern:

Be it known that we, MIGAGAH COLLINS and BENJAMIN A. LILLIE, ofPortland, in the county of Multnomah and State of Oregon, have inventeda new and valuable Improvement in Reversible Spring Bed-Bottoms; and wedo hereby declare that the following is a full, clear, and exactdescription of theconstruction and operation of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure l of the drawing isa representation of an inverted plan view ofour spring bedbottom, and Fig. 2 is a side elevation of the same.

head and foot strips, each of which is provided r with a series of studsor pegs, b, at equal distances apart, and projecting on both upper andunder sides, in order that these strips, as well as the bed-slats, maybe reversed or turned when, from the constant pressure, they have lost,in a measure, their elasticity and acquired a permanent downwardflexure.

The head and foot strips may be, with advantage, made wider at themiddle than at the ends, with a gradual taper. In this mannor thecentral portions, which are unsupported, will be strong enough tosustain the weight as well as the end portions, which rest upon thehearings or supports. By a proper disposition of the material, verylittle waste need occur in cutting strips of this shape.

It is apparent that all the springs of this bed-bottom can be turned ina few minutes, and its elasticity and firmness renewed.

What we claim as new, and desire to secure by Letters Patent, is-

In a bed-bottom, the reversible tapering bars 0, provided with series ofpins 1), in combination with the reversible perforated slats B,substantially as described.

In testimony that we claim the above we have hereunto subscribed ournames in the presence of two witnesses.
